INTRODUCTION
INTRODUCTION
Thank You
for purchasing a Gorman-Rupp JS or
JSV Series FM-Approved Pump.
Read this manu-
al
carefully to learn how to safely install and oper-
ate your pump. Failure to do so could result in per-
sonal injury or damage to the pump.
A set of three manuals accompanies your pump.
Each set consists of three parts; the Installation/
Operation Manual contains essential information
on installing and operating the pump, and on mak-
ing electrical connections. However, since pump
installations are seldom identical, some of the in-
formation only summarizes general recommenda-
tions and practices required to inspect, position,
and arrange the pump and piping.
The Parts List Manual provides performance
curve(s), a pump model cross-section drawing,
and parts list for your pump.
The Maintenance and Repair Manual provides
troubleshooting and maintenance instructions re-
quired to properly diagnose operational problems,
and to service the pump hydraulic components.
Pump motor maintenance may be performed
only
by a Gorman-Rupp authorized repair facility, or the
factory. Otherwise, the pump warranty will be ne-
gated, and damage to the pump, and injury or
death to personnel can result. Contact the factory
for the authorized repair facility closest to you.
The pump is driven by an explosion-proof, sub-
mersible electric motor, FM-approved for Class 1,
Division 1, Group C and D locations. If the motor is
dual-voltage, the pump is shipped from the factory
wired
only
for the voltage shown on the name-
plate. If desired to have the voltage changed, re-
turn the pump to the factory or to a Gorman-Rupp
authorized repair facility.
The pump motor
must
be operated through an ap-
propriate control box matching the voltage and
other characteristics of the motor. The control box
must be approved by Gorman-Rupp for the appli-
cation and environment intended, and must also
provide for proper operation of the motor protec-
tion devices, such as the integral moisture and
thermal switches. Control boxes and other control
devices not integral to the pump are
no
t covered
in this manual.
Pump construction is cast iron, with stainless steel
shaft and hardware. These pumps are equipped
with a guide shoe for mounting on guide rails in a
wet well. A guide rail system, controls and liquid
level devices are available from the factory as op-
tional equipment.
If there are any questions regarding the pump
which are not covered in this manual or in other lit-
erature accompanying the unit, please contact
your Gorman-Rupp distributor or the Gorman-
Rupp Company:
